[qanda]This thread is about the NEC ND-3550 DVD-RW Black. Click here to see full specs[/qanda]My NEC DVD_RW ND-3550 (firmware ver 1.07) DL DVD burner has started to not recognize about half of the factory DVD’s. When I click on the drive, it tells me to insert a disc. I can take the disc out of my the drive in put in a Dell or HP laptop, that has no problem recognizing the disc.
I can put another factory DVD or my burned DVD (Verbatim DVD+R) in the NEC 3550, and it reads them without a problem. Every DVD burned can be read by any DVD player. I am running Windows XP64 Professional. A friend that has a Sony Optiarc is having exactly the same problem. He is running Windows XP(32) Professional.
We are both running antivirus, malware, and spybot software protection programs, and scan our systems regularly. We have both tried cleaning the discs, rebooting the systems, updating our firmware, removing and reinstalling the drives, which has made no difference. Searching the net, I found forums where others were having the same problem. It seems many that reply, don’t read the problem, because their answers are: update the firmware, use good discs, or remove and reinstall the drive.
On one site, the poster said to try reinstalling Adaptec lastest ASPI drivers. I went to Adaptec, grabbed the latest XP version (471a2.exe), and tried to run the self-extracting install, that gave me the message that that version was not for my system. I got a copy of the Nero ASPI drivers, which said XP did not need it, and that it was only necessary on 98 or Me. Regardless, I don’t know if this is the problem or not.
When I go to the Device Manager and bring up the IDE ATA/ATAPI controllers properties, the General Tab says “The device is working properly”. When I click the Advanced Settings tab, Transfer Mode is set to DMA if available, however the Current Transfer Mode is shown as PIO mode. DMA is enabled in the bios. When I click on the NEC DVD_RW and select Properties, again it says “The device is working properly”.
I have tried to stick to the facts and explain this as straight forward as possible. Is there anyone else having this problem, or aware of a fix for it?
